TPS71229 - Texas Instruments

TPS71229 Low-Dropout Linear Regulator

The TPS712xx family of low-dropout (LDO) voltage regulators is tailored to noise-sensitive and RF applications. These products feature dual 250 mA LDOs with ultralow noise, high power-supply rejection ratio (PSRR), and fast transient and start-up response. Each regulator output is stable with low-cost 2.2 mF ceramic output capacitors and features very low dr.
