HIGH RIPPLE-REJECTION SMALL PACKAGE CMOS VOLTAGE REGULATOR Rev.4.2_00 S-1323 Series Precautions
Wiring patterns VIN, VOUT pins should designed that impedance low. When mounting output capacitor between VOUT pins (CL) capacitor stabilizing input between pins (CIN), distance from capacitors these pins should short possible. Note that output voltage increase when series regulator used load current (1.0 less). Generally series regulator cause oscillation, depending selection external parts. following conditions recommended this However, sure perform sufficient evaluation under actual usage conditions selection, including evaluation temperature characteristics. Input capacitor (CIN): more Output capacitor (CL): more Equivalent series resistance (ESR): less voltage regulator oscillate when impedance power supply high input capacitor small input capacitor connected. application conditions input voltage, output voltage, load current should exceed package power dissipation. apply electrostatic discharge this that exceeds performance ratings built-in electrostatic protection circuit. determining output current, attention should paid output current value specified Table electrical characteristics footnote table. claims responsibility disputes arising connection with infringement products including this patents owned third party.
