Symbol
Function
1
ENA
Enable Regulator A pin; this pin should not be left floating. When pulled
low, the PMOS pass transistor turns off and the device enters shutdown
mode, consuming less than 1µA.
2, 3, 8, 9
GND
Ground connection pins.
4
POKA
Power OK pin with open drain output. It is pulled low when the OUTA pin is
below the 10% regulation window.
5
OUTB
Low current (150mA) regulator output pin; should be decoupled with a
2.2µF or greater output low-ESR ceramic capacitor.
6
INB
Input voltage pin for Regulator B; should be decoupled with 1µF or greater
capacitor.
7
ENB
Enable Regulator B; this pin should not be left floating. When pulled low, the
PMOS pass transistor turns off and the device enters shutdown mode, con-
suming less than 1µA.
10
POKB
Power OK pin with open drain output. It is pulled low when the OUTB pin is
below the 10% regulation window.
11
OUTA
High-current (300mA) regulator output pin; should be decoupled with a
2.2µF or greater output low-ESR ceramic capacitor.
12
INA
Input voltage pin for Regulator A; should be decoupled with 1µF or greater
capacitor.
