NAME
FUNCTION
1
1
OUTB
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).
2
2
GND
Ground. This pin also functions as a heatsink. Solder to a large pad or the
circuit-board ground plane to maximize thermal dissipation.
3
BP
Reference Noise Bypass. Bypass with a low-leakage 0.01
μ
F ceramic
capacitor for reduced noise at both outputs.
3
SHDNA
Shutdown A Input. A logic low shuts down regulator A. If
SHDNA
and
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.
4
SHDNB
Shutdown B Input. A logic low shuts down regulator B. If
SHDNA
and
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.
4
SHDN
Shutdown Input. A logic low shuts down both regulators and the reference,
reducing the entire supply current to 10nA. Connect to IN for normal
operation.
5
5
IN
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).
6
6
OUTA
Regulator A 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).
