GENERAL DESCRIPTION
XC6216/XE6216 series are highly precise, low noise, positive regulator ICs. The series consists of a voltage reference, an error amplifier, a current limiter, a thermal shutdown circuit and a phase compensation circuit plus a driver transistor. The output voltage is selectable in 100mV increments within the range of 2.0V to 12V using laser trimming technologies (XC6216B/XE6216B series). Furthermore, with external resistors, the output voltage can be set from 2.0V to 23V (XC6216C/XE6216E series). The series' output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current reaches current limit level or the junction temperature reaches temperature limit level. The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power consumption.

PIN CONFIGURATION
* The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking so as to enhance mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the VSS (PIN # 5).

OPERATIONAL EXPLANATION
The voltage divided by resistors R11 & R12 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET, which is connected to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current and heat dissipation. Further, the IC's internal circuitry can be shutdown via the CE pin's signal.

The XC6216/XE6216 series includes a current limit circuit, which aid the operations of the current limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. The output voltage drops further and output current decreases. When the output pin is shorted, a current of about 30mA flows. The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6216/XE6216 series. In shutdown mode, output at the VOUT pin will be pulled down by R11 and R12 to the VSS level. Note that as the standard XC6216/XE6216 series is `High Active/No pull down', operations will become unstable with the CE pin open. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry if a medium voltage is applied. When the junction temperature of the built-in driver transistor reaches the temperature limit level (150 TYP.), the thermal shutdown circuit operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown function is released and the IC's operation is automatically restored because the junction temperature drops to the level of the thermal shutdown release voltage. For the stable operation of the IC, over 2.0V of input voltage is necessary. The output voltage may not be generated normally if the input voltage is less than 2.0V.
NOTES ON USE
1 Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded. 2 Where wiring impedance is high, operations may become unstable due to the noise and/or phase lag depending on output current. Please strengthen VIN and VSS wiring in particular. 3. Phase compensation inside the IC is performed in the XC6216/XE6216 series. Therefore, an abnormal oscillation does not occur even if there is no output capacitor CL. An input capacitor CIN around 0.1uF~1.0uF between the VIN pin and the VSS pin is required for input stability. Also, the output voltage fluctuation such as under shoot or over shoot, which occurs because of the load change can be controlled by placing the output capacitor CL around 0.1uF~1.0uF between the VOUT pin and VSS pin. The input capacitor (CIN) and the output capacitor (CL) should be placed to the IC as close as possible with a shorter wiring.
