TPS7148QDG4
低压差稳压器 LOW-DROPOUT VOLTAGE REGULATORS
description
The TPS71xx integrated circuits are a family of micropower low-dropout LDO voltage regulators. An order of magnitude reduction in dropout voltage and quiescent current over conventional LDO performance is achieved by replacing the typical pnp pass transistor with a PMOS device.
Available in 5-V, 4.85-V, and 3.3-V Fixed-Output and Adjustable Versions
Very Low-Dropout Voltage . . . Maximum of 32 mV at IO = 100 mA TPS7150
