Renesas Electronics Corporation Voltage Regulators - Linear ISL9012IRKCZ-T

The ISL9012IRKCZ-T 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 range of load current. The ISL9012IRKCZ-T includes a programmable power-on-reset (POR) function for the VO2 output, adjustable by connecting a timing capacitor to the CPOR pin. It supports output capacitance from 1µF to 10µF with an equivalent series resistance (ESR) of up to 200mΩ, ensuring stability. The device also features separate enable pins for each LDO, allowing for independent control, and a shutdown mode that reduces current draw to less than 0.1µA. This regulator is suitable for applications in portable devices such as PDAs, smartphones, and handheld medical instruments, operating effectively within a temperature range of -40°C to +85°C. The compact 10-lead 3x3mm DFN package makes it a space-efficient choice for various electronic designs.
