FEATURES
DESCRIPTION
20V High Efficiency
Nanopower
Step-Down Regulator
The LTC3388-1/LTC3388-3 are high efficiency step-down
DC/DC converters with internal high side and synchronous
power switches that draw only 720nA typical DC sup-
ply current at no load while maintaining output voltage
regulation.
Capable of supplying 50mA of load current, the LTC3388-1/
LTC3388-3 also incorporate an accurate undervoltage lock-
out (UVLO) feature to disable the converter and maintain
a low quiescent current state when the input voltage falls
below 2.3V. In regulation, the LTC3388-1/LTC3388-3 enter
a sleep state in which both input and output quiescent cur-
rents are minimal. The buck converter turns on and off as
needed to maintain regulation. An additional standby mode
disables buck switching while the output is in regulation
for short duration loads requiring low ripple.
Output voltages of 1.2V, 1.5V, 1.8V, 2.5V (LTC3388-1) and
2.8V, 3.0V, 3.3V, 5.0V (LTC3388-3) are pin selectable. The
LTC3388-1/LTC3388-3 can operate with VINupto20Vwhile
the no load quiescent current remains below 1μA.
