| MITSUBISHI PRELIMINARY M62520FP HIGH PRECISION LOW INPUT/OUTPUT DIFFERENTIAL 3.3V FIXED OUTPUT VOLTAGE REGULATOR WITH RESET Some parametric limits are subject to change. PIN CONFIGURATION(TOP VIEW) DESCRIPTION M62520FP is monolithic integrated circuit integrating high precision regulator and reset IC targeted for printer, CD-ROM, CD-R, and the other OA equipments. This regulator features high precision output, low input/output differential, high current capability, and high ripple rejection ratio. Compact application design is made easy by small 8pin package. FEATURES *High precision output voltage-----3.3V2% *High output current-----------300mA(max.) *High ripple rejection ratio--------80dB(typ.) *Low input/output differential--- 0.3V(typ.)(IL=150mA) *Small limiting current due to shorted loads by drooping fold-back protection------------ 20mA(typ.) *Load regulation----------------30mV(typ.) *ON/OFF control available for regulator output *Non-adjustment for reset detection voltage----3.9V2% *Reset--monitors input voltage 5V APPLICATION OA equipments such as printer, CD-ROM, and so forth NC 1 Reset output 2 8 7 6 5 Cd GND NC Reg. output ON/OFF 3 VIN 4 Outline 8P2S-A 4 + - VIN Err.

R is a pull-up resistance for reset terminal. 2.2kohm is recommended for the value. Note2. C1 works for stabilizing input voltage. Recommended value is 10uF. Note3. Co works for preventing the output voltage from oscillation. Minimum value is 10uF. Recommended value is 47uF. Note4. Delay time for reset is changeable by the capacitance connected to Cd terminal. Even when no capacitor is connected, 30usec.(typ.) delay time is available. Below shows how to set the delay time. Delay time:Tpd(ms)=100xCd(F) Example:when 0.1uF is connected to Cd terminal. Tpd(ms)=100x0.1(F) =10 (ms) Note5. Connect ON/OFF terminal and VIN when ON/OFF function is not needed. Note6. Get the capacitors close to IC terminals in case the operation is not stabilized by the wiring resistance between each capacitor and IC terminals. ( 4 /4) 000512 |
