Pololu 3.3V Step-Up/Step-Down Voltage Regulator w/ Adjustable Low-Voltage Cutoff S9V11F3S5CMA

Pololu 3.3V Step-Up/Step-Down Voltage Regulator w/ Adjustable Low-Voltage Cutoff S9V11F3S5CMA

The S9V11F3S5CMA switching step-up/step-down regulator efficiently produces a fixed 3.3 V (default) or 5 V (selectable) output whether it is higher or lower than the input voltage, which can range from 2 V to 16 V. (Note: minimum start-up voltage is 3 V, but it operates to 2 V after that.) The regulator also has a precision-adjustable low-voltage cutoff with hysteresis that can be used to prevent battery over-discharge. The compact (0.5? × 0.6?) module can supply a typical output current of up to 1.5 A when the input voltage is close to the output voltage.

Features

Input voltage: 2 V to 16 V
Fixed 3.3 V output with +5/-3% accuracy (can be changed to 5 V using the SEL pin)
Typical maximum continuous output current: 1.5 A (when input voltage is close to the output; the Typical efficiency and output current section below shows how the achievable continuous output current depends on the input and output voltages)
Precision-adjustable low-voltage cutoff with hysteresis can be used to protect batteries from over-discharging (quiescent current is approximately 10 µA per volt on VIN when regulator is disabled)
Power-good indicator can be used to tell when the regulator has reached and is maintaining its target output voltage
Power-saving feature maintains high efficiency at low currents (quiescent current is less than 1 mA while enabled)
Integrated over-temperature and short-circuit protection
Small size: 12.7 × 15.3 × 6.4 mm
Weight: 0.8 g ?Without included optional headers.?

General specifications
