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

The S9V11MACMA switching regulator efficiently generates a finely adjustable output voltage between 2.5 V and 9 V, whether that is higher or lower than the input voltage, which can range from 3 V to 16 V. The regulator also features a precisely adjustable low-voltage cutoff with hysteresis, which can be used to prevent battery over-discharge. The compact module can deliver an 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 needs 3 V to start, but can operate down to 2 V after startup)
• Output voltage: 2.5 V to 9 V (precisely adjustable via built-in 12-turn potentiometer)
• Typical maximum continuous output current: 1.5 A (when the input voltage is close to the output)
• A precisely adjustable low-voltage cutoff with hysteresis can be used to protect the batteries from over-discharge (the quiescent current is approx. 10 ?A per volt on VIN when the regulator is disabled)
• The power-good indicator can be used to detect when the regulator has reached and is maintaining its target output voltage
• Power-save feature maintains high efficiency at low current (quiescent current is less than 1 mA while enabled)
• Integrated over-temperature and short-circuit protection
• Size: 12.7 × 15.3 × 6.4 mm
