The S9V11MAswitchingstep-up/step-down regulator efficiently produces a finely adjustable output between 2.5 V and 9 V 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 compact 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
Output voltage: 2.5 V to 9 V (precision-adjustable using built-in 12-turn potentiometer)
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)
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 and approximately 7 µA per volt on VIN when regulator is disabled)
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

Minimum operating voltage: 2 V (Note: the minimum startup voltage is 3V, but the regulator can operate down to 2V after startup.)
Maximum operating voltage: 16 V
Maximum output current: 1.5 A (Under typical conditions, where the input voltage is close to the output voltage. Maximum output current can be higher when stepping down and lower when stepping up.)
Minimum output voltage: 2.5 V
Maximum output voltage: 9 V (Output voltage is set by a built-in precision 12-turn potentiometer.)
Reverse voltage protection?: N
Maximum quiescent current: 1 mA (With no load. Actual quiescent current depends on input voltage; it is typically under 300 µA when the input voltage is close to the output voltage.)
