The LT(R)1033 negative adjustable regulator will deliver up to 3A output current over an output voltage range of -1.2V to -32V. Linear Technology has made significant improvements in these regulators compared to previous devices, such as better line and load regulation, and a maximum output voltage error of 1%. The LT1033 is easy to use and difficult to damage. Internal current and power limiting as well as true thermal limiting prevents device damage due to overloads or shorts, even if the regulator is not fastened to a heat sink. Maximum reliability is attained with Linear Technology's advanced processing techniques combined with a 100% burn-in in the thermal limit mode. This assures that all device protection circuits are working and eliminates field failures experienced with other regulators that receive only standard electrical testing.

Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: Unless otherwise indicated, these specifications apply: |VIN - VOUT| = 5V; and IOUT = 5mA. Power dissipation is internally limited. However, these specifications apply for power dissipation up to 30W.
See guaranteed minimum output current curve. IMAX = 3A. Note 3: Testing is done using a pulsed low duty cycle technique. See thermal regulation specifications for output changes due to heating effects. Load regulation is measured on the output pin at a point 1/8" below the base of the package.

APPLICATIONS INFORMATION
Output Voltage The output voltage is determined by two external resistors, R1 and R2 (see Figure 1). The exact formula for the output voltage is: R2 VOUT = VREF 1 + + IADJ (R2) R1 Where: VREF = Reference Voltage, IADJ = Adjustment Pin Current. In most applications, the second term is small enough to be ignored, typically about 0.5% of VOUT. In more critical applications, the exact formula should be used, with IADJ equal to 65A. Solving for R2 yields: R2 = VOUT - VREF VREF - IADJ R1 which must be absorbed, is 5mA for the LT1033. If inputoutput voltage differential is less than 10V, the operating current that must be absorbed drops to 3mA. Capacitors and Protection Diodes An output capacitor, C3, is required to provide proper frequency compensation of the regulator feedback loop. A 2F or larger solid tantalum capacitor is generally sufficient for this purpose if the 1MHz impedance of the capacitor is 1 or less. High Q capacitors, such as Mylar, are not recommended because their extremely low ESR (effective series resistance) can drastically reduce phase margin. When these types of capacitors must be used because of other considerations, add a 0.5 carbon resistor in series with 1F. Aluminum electrolytic capacitors may be used, but the minimum value should be 25F to ensure a low impedance at 1MHz. The output capacitor should be located within a few inches of the regulator to keep lead impedance to a minimum. The following caution should be noted: if the output voltage is greater than 6V and an output capacitor greater than 20F has been used, it is possible to damage the regulator if the input voltage becomes shorted, due to the output capacitor discharging into the regulator. This can be prevented by using diode D1 (see Figure 2) between the input and the output. The input capacitor, C2, is only required if the regulator is more than 4 inches from the raw supply filter capacitor. Bypassing the Adjustment Pin The adjustment pin of the LT1033 may be bypassed with a capacitor to ground, C1, to reduce output ripple, noise, and impedance. These parameters scale directly with output voltage if the adjustment pin is not bypassed. A bypass capacitor reduces ripple, noise and impedance to that of a 1.25V regulator. In a 15V regulator for example, these parameters are improved by 15V/1.25V = 12 to 1. This improvement holds only for those frequencies where the impedance of the bypass capacitor is less than R1. Ten microfarads is generally sufficient for 60Hz power line applications where the ripple frequency is 120Hz, since XC = 130. The capacitor should have a voltage rating at least as high as the output voltage of the regulator. Values
1033fc
Smaller values of R1 and R2 will reduce the influence of IADJ on the output voltage, but the no-load current drain on the regulator will be increased. Typical values for R1 are between 100 and 300, giving 12.5mA and 4.2mA no-load current respectively. There is an additional consideration in selecting R1, the minimum load current specification of the regulator. The operating current of the LT1033 flows from input to output. If this current is not absorbed by the load, the output of the regulator will rise above the regulated value. The current drawn by R1 and R2 is normally high enough to absorb the current, but care must be taken in no-load situations where R1 and R2 have high values. The maximum value for the operating current,

APPLICATIONS INFORMATION
larger than 10F may be used, but if the output is larger than 25V, a diode, D2, should be added between the output and adjustment pins (see Figure 2).

Proper Connection of Divider Resistors The LT1033 has a load regulation specification of 0.8% and is measured at a point 1/8" from the bottom of the package. To prevent degradation of load regulation, the resistors which set output voltage, R1 and R2, must be connected as shown in Figure 3. Note that the positive side of the load has a true force and sense (Kelvin) connection, but the negative side of the load does not. R1 should be connected directly to the output lead of the regulator, as close as possible to the specified point 1/8" from the case. R2 should be connected to the positive side of the load separately from the positive (ground) connection to the raw supply. With this arrangement, load regulation is degraded only by the resistance between the regulator output pin and the load. If R1 is connected to the load, regulation will be degraded.

TYPICAL APPLICATIO S
The output stability, load regulation, line regulation, thermal regulation, temperature drift, long term drift, and noise can be improved by a factor of 6.6 over the standard regulator configuration. This assumes a zener whose drift and noise is considerably better than the regulator itself. The LM329B has 20ppm/C maximum drift and about 10 times lower noise than the regulator. In the application shown below, regulators #2 to "N" will track regulator #1 to within 24mV initially, and to 60mV over all load, line, and temperature conditions. If any regulator output is shorted to ground, all other outputs will drop to -2V. Load regulation of regulators #2 to "N" will be improved by VOUT/1.25V compared to a standard regulator, so regulator #1 should be the one which has the lowest load current.
