Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9003IENZ-T

ISL9003IENZ-T

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ISL9003IENZ-T is a single-output low dropout linear regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 3.3V with a maximum continuous load current of 150mA. The device operates within an input voltage range of 2.3V to 6.5V and maintains ±1.8% accuracy across the full operating temperature range of -40°C to +85°C. Key electrical characteristics include a typical quiescent current of 30µA, a shutdown current of 0.5µA, and a ripple rejection ratio of 90dB at 1kHz. The regulator is stable with 1µF to 4.7µF ceramic output capacitors.
