TPS71025 LOW-DROPOUT VOLTAGE REGULATOR

The TPS71025 low-dropout regulator offers an order of magnitude reduction in both dropout voltage and quiescent current over conventional LDO performance. The improvement results from replacing the typical pnp pass transistor with a PMOS device. D OR P PACKAGE (TOP VIEW) GND EN IN IN 1 2 3 4 8 N.
