TPS71025 Datasheet (Texas Instruments) - LOW-DROPOUT VOLTAGE REGULATOR

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.
