TPS72301DDCT TI Negative LDO Regulator | SOT-23-THIN | -3V to -10V, 200mA

Product Overview

The TPS72301DDCT from Texas Instruments is a negative-voltage, low-dropout (LDO) linear regulator designed for applications requiring a regulated negative output voltage. It delivers up to 200 mA of output current with a dropout voltage of typically 220 mV at full load. The output voltage is adjustable from -3 V to -10 V using an external resistor divider. The device features a low quiescent current of 85 µA (typical) and a shutdown mode that reduces supply current to less than 1 µA. It is available in a thin SOT-23 (SOT-23-THIN) package, making it suitable for space-constrained designs.
