NAME
FUNCTION
Regulator B Output. Sources up to 160mA continuous current. Bypass with a

2.2 μ F (<0.5 ? typ ESR) capacitor to GND (see the Capacitor Selection and
Regulator Stability section).

Ground. This pin also functions as a heatsink. Solder to a large pad or the
circuit-board ground plane to maximize thermal dissipation.
Reference Noise Bypass. Bypass with a low-leakage 0.01 μ F ceramic
capacitor for reduced noise at both outputs.
Shutdown A Input. A logic low shuts down regulator A. If SHDNA and
3
SHDNA
SHDNB are both low, both regulators and the reference turn off, and supply
current is reduced to 10nA. If either SHDNA or SHDNB is a logic high, the
reference is on. Connect to IN for normal operation.
Shutdown B Input. A logic low shuts down regulator B. If SHDNA and
4
SHDNB
SHDNB are both low, both regulators and the reference turn off, and supply
current is reduced to 10nA. If either SHDNA or SHDNB is a logic high, the
reference is on. Connect to IN for normal operation.
Shutdown Input. A logic low shuts down both regulators and the reference,
4
SHDN
reducing the entire supply current to 10nA. Connect to IN for normal
operation.
Regulator Input. Supply voltage can range from +2.5V to +6.5V. This input

also supplies the on-chip reference. Bypass with 2.2 μ F to GND (see the
Capacitor Selection and Regulator Stability section).
Regulator A Output. Sources up to 160mA continuous current. Bypass with

OUTA
a 2.2 μ F (<0.5 ? typ ESR) capacitor to GND (see the Capacitor Selection and
Regulator Stability section).
