Description
The LT3021 is a low-noise, precision low-dropout (LDO) regulator from Linear Technology. LT3021EDH#TRPBF is that device in the EDH package, delivered in Tape-and-Reel Pb-Free packaging. It can be configured for fixed or adjustable output using external resistors, and includes an enable/shutdown input. The part is designed for low quiescent current, good line/load regulation, and stable operation in space-constrained, portable analog supplies. Typical uses include providing clean Vout rails for microcontrollers, sensors, and analog circuits in battery-powered devices. Pinout and exact electrical specs (output voltage options, dropout, PSRR, quiescent current) vary by variant; the EDH suffix only denotes the packaging. For precise details, consult the LT3021 datasheet and the product page. If you share your target output voltage, I can point to the exact variant and a basic application sketch.
