Renesas Electronics Corporation Voltage Regulators - Linear ISL9012IRPLZ

The ISL9012IRPLZ is a dual low-dropout (LDO) voltage regulator from Quarktwin Technology Ltd. It provides two output channels, capable of sourcing 150mA from Channel 1 and 300mA from Channel 2. The device operates within a wide input voltage range of 2.3V to 6.5V and features a low quiescent current of 45µA when both LDOs are active. It is designed for high performance with a high power supply rejection ratio (PSRR) of 70dB at 1kHz and excellent load regulation of 1% across the full load current range. The ISL9012IRPLZ includes a programmable power-on-reset (POR) function for the VO2 output, allowing for customizable delay times. It is stable with output capacitance ranging from 1µF to 10µF and can handle an equivalent series resistance (ESR) of up to 200mΩ. The device also features separate enable pins for each LDO, a soft-start function to limit input current surge, and built-in current limit and overheat protection. It is packaged in a compact 10-lead 3x3mm DFN format and operates over a temperature range of -40°C to +85°C. This regulator is suitable for applications in portable devices such as PDAs, smartphones, and handheld medical instruments.
