Description
Regulator 2 Output. Sources up to 150mA continuous
current. Bypass with a 1µF (< 0.5Ω typ ESR) capacitor to
GND.
Ground. This pin also functions as heatsink. Solder to a
large pad or the circuit-board ground plane to maximize
thermal dissipation.
Reference Noise Bypass. Bypass with a low leakage 10nF
ceramic capacitor for reduced nise at both outputs.
Shutdown 1 Input. A logic low shuts down regulator 1.
If EN1 and EN2 are both low, both regulators and the
reference turn off. If either EN1 and EN2 is a logic high,
the reference is on. Connect to V_IN for normal operation.
Shutdown Input. A logic low shuts down both regulators.
Connect to V_IN for normal operation.
Shutdown 2 Input. A logic low shuts down regulator 2.
If EN1 and EN2 are both low, both regulators and the
reference turn off. If either EN1 and EN2 is a logic high,
the reference is on. Connect to V_IN for normal operation.
Regulator Input. Supply voltage can range from Higher
V_OUT+V_DROPOUT to 5.5V. This input also supplies the on-
chip reference. Bypass with 1µF to GND.
Regulator 1 Output. Sources up to 150mA continuous
current. Bypass with a 1µF (< 0.5Ω typ ESR) capacitor to
GND.
