Pin Descriptions
OUT1 - This pin is the output for LDO1. Bypass with a
minimum of 2.2F, low ESR capacitor to GND for stable
operation.
VIN - Supply input pins. Connect to input power source.
Bypass with a minimum 2.2
μF capacitor to GND. Both V
IN
pins must be tied together on the PC board, close to the IC.
GND - Ground for LDO1 and LDO2.
CC1 - Compensation Capacitor for LDO1. Connect a
0.033F capacitor from CC1 to GND.
SHDN - Shutdown input for all LDOs. Connect to VIN for
normal operation. Drive this pin LOW to turn off all LDOs.
OUT2 - This pin is the output for LDO2. Bypass with a
minimum of 2.2F, low ESR capacitor to GND for stable
operation.
CT - Timing pin for the RESET circuit pulse width.
CC2 - Compensation capacitor for LDO2. Connect a
0.033F capacitor from CC2 to GND.
OUT3 - This pin is output for LDO3. Bypass with a minimum
of 2.2F, low ESR capacitor to GND3 for stable operation.
GND3 - Ground pin for LDO3.
CC3 - Compensation capacitor for LDO3. Connect a
0.033F capacitor from CC3 to GND3.
FAULT1 - This is the power good indicator for LDO1. When
the 1.8V output is out of regulation this pin goes LOW. This
