ISL9012IRJCZ

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

The ISL9012IRJCZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDO channels within a compact 10-lead, 3x3mm DFN package. Channel 1 (VO1) provides a fixed output voltage of 2.8V with a maximum continuous current capability of 150mA. Channel 2 (VO2) delivers a fixed output voltage of 1.8V with a maximum continuous current capability of 300mA. The device operates over an input voltage range of 2.3V to 6.5V and supports an ambient operating temperature range from -40°C to +85°C.

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

How is the Power-On Reset (POR) delay configured?

The POR delay for the VO2 output is externally programmed by connecting a timing capacitor between the CPOR pin and ground. A 0.01µF capacitor results in approximately a 200ms delay.

What is the recommended output capacitance range?

The device is stable with output capacitance values ranging from 1µF to 10µF, provided the equivalent series resistance (ESR) is less than 200mΩ.
