Overview
The TPS715A01DRVR is a low-dropout (LDO) linear voltage regulator produced by Texas Instruments. This device is designed to offer a wide input voltage range, low quiescent current, and high efficiency, making it ideal for battery-powered applications and power management in low-power microcontrollers.
The TPS715A01DRVR is available in both fixed and adjustable output voltage versions, with the adjustable version allowing for output voltages from 1.205 V to 15 V using external feedback resistors. The device features a very low quiescent current of 3.2 μA at an 80-mA load current, ensuring minimal power consumption.
The regulator is packaged in a compact 2-mm × 2-mm WSON (DRV) package, suitable for high power dissipation and ultra-portable applications. It also includes internal soft-start to control inrush current and built-in overcurrent protection to safeguard against load shorts or faults.
