Product Overview
The TLV757P is a Texas Instruments Power_Management power IC specified as a 1A low-dropout regulator. The device operates from a 1.45 to 5.5 V recommended input range and supports fixed-output versions from 0.6 to 5.0 V in 50 mV steps. Recommended output current spans 0 to 1 A, with typical quiescent current listed at 25 uA at TJ = 25°C.
Electrical behavior includes output accuracy limits for both VOUT above and below 1 V, 2 mV typical line regulation, package-dependent load regulation, 1.55 A typical current limit, and 755 mA typical short-circuit current limit. Dropout voltage is specified at 300 mV typical for 1 A conditions, with package and temperature-dependent maximum ratings.
The TLV757P is available in SOT-23-5 DBV, SOT-23-5 DYD with thermal pad, and WSON-6 DRV packages. It requires a nominal 1 uF input capacitor and supports 1 to 200 uF output capacitance with effective capacitance above 0.47 uF. Application fit is based on regulated low-voltage rails requiring enable control, shutdown mode, ceramic output capacitor stability, and defined thermal limits.
