TPS71202-EP - Texas Instruments

TPS71202-EP LOW-DROPOUT LINEAR REGULATOR

The TPS71202 low-dropout (LDO) voltage regulator is tailored to noise-sensitive and RF applications. It features dual 250-mA LDOs with ultra-low 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 dropout voltages (125 m.
