1 Overview

The TPS73801-SEP is a radiation hardened, 1A, low dropout (LDO) regulator optimized for fast transient response. At a load of 1A, the device typically features 300mV of dropout. In addition to fast transient response, the LDO features low output noise, making the device designed for sensitive RF applications. Quiescent current is well controlled and does not rise in dropout. Additional features of the device are reverse battery and current protection, thermal shutdown, and current limiting. The device is offered in a plastic 6-pin DCQ (SOT-223) package.

General device information and test conditions are listed in Table 1-1. For more detailed technical specifications, EVM user guides, and application notes, please see the TPS73801-SEP product page
