PIN DESCRIPTIONS
Pin # Pin Name
Pin Function
1
OUTA Regulator A output.
2
OUTB Regulator B output.
3
GND Ground pin.
4
RSTA Power on reset for regulator A. Active low when OUTA is below the reset threshold.
5
RSTB Power on reset for regulator B. Active low when OUTB is below the reset threshold.
6
DLYB Programmable delay for RESETB. Delay time can be set by connecting a capacitor, CDLYB, be-
tween this pin and ground. Ground this pin if using the default delay time.
7
ENB Active high enable pin for output B. CMOS compatible input. Connect to IN if not being used.
8
BYP Bypass pin for bandgap reference. Connect a 10nF capacitor, CBYP, between this pin and
ground for low noise operation.
9
ENA Active high enable pin for output A. CMOS compatible input. Connect to IN if not being used.
10
IN Input pin for both regulators.
