2.5-9V Fine-Adjust Step-Up/Down Voltage Regulator w/ Adjustable Low-Voltage Cutoff S9V11MACMA Pololu 2868

The S9V11MACMA switching step-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 3 V to 16 V. 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 (note: this regulator requires 3 V to start, but it can operate down to 2 V after startup)
• 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)
• 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: 0.5″ × 0.6″ × 0.25″ (12.7 × 15.3 × 6.4 mm)
