Texas Instruments TPS2141 Adjustable LDO Plus 5V Switch with Dual Current Limit for High Power USB Peripherals TPS2141IPWPRG4

The TPS2141IPWPRG4 is an adjustable low-dropout (LDO) regulator combined with a 5V power switch, designed specifically for high-power USB peripherals. It features a maximum output current of 250 mA for the LDO and a typical current limit of 325 mA, with the capability to handle up to 800 mA during higher load conditions. The input voltage range for the LDO is from 2.7 V to 5.5 V, while the adjustable output voltage can be set between 0.9 V and 3.3 V. This device includes dual current limiting for the switch, which helps manage inrush current and allows for the use of high-value capacitance at the output. It also incorporates undervoltage lockout and power good indicators for both the LDO and the switch, enhancing system reliability. The TPS2141IPWPRG4 operates with a low supply current of 85 µA and a standby current of just 5 µA, making it suitable for power-sensitive applications. It is packaged in a 14-pin HTSSOP format and is rated for operation in ambient temperatures from -40°C to +85°C. This product is particularly well-suited for applications such as ADSL modems, digital cameras, and other USB peripherals requiring efficient power management.
