LD39020DTPU47R ST LDO Regulator | 4-DFN(1x1) | 200mA, 4.7V Output

Product Overview

The LD39020DTPU47R is a high-performance, low-dropout (LDO) voltage regulator from STMicroelectronics, designed to deliver up to 200 mA output current with a fixed output voltage of 4.7 V. Housed in a compact 4-lead DFN package (1x1 mm), this device is ideal for space-constrained applications requiring low quiescent current and high power supply rejection ratio (PSRR). The LD39020 series offers excellent line and load transient response, making it suitable for powering sensitive analog and digital circuits.
