PMIC – Voltage Regulators – Linear

The ISL9012IRLLZ-T is an integrated linear voltage regulator used for power management in handheld and portable devices. It operates from 1.7V to 6V and provides up to 130mA of output current. It is designed to provide a low-noise output voltage and is available in a small 2mm x 2mm TDFN package.

Application Field and Working Principle

The primary application fields for the ISL9012IRLLZ-T are portable systems, such as in PCMCIA cards, cell phones, digital cameras, and other portable devices. The low-noise output voltage and small package size make this device ideal for handheld and portable applications.The working principle of the device is that it takes a DC input voltage and supplies a DC output voltage. The device consists of an internal N-type MOSFET connected in series between the input and output terminals. The voltage across this MOSFET is regulated by varying the gate voltage. The internal P-type MOSFET senses the output current and limits it to the maximum value by turning on when the current reaches the maximum limit.

The device is designed to maintain stability and provide accurate regulation over wide input and output voltage and load variations. Additionally, the device features additional features such as thermal shut down, over-temperature protection, over-current protection, and low-power shutdown. The low dropout voltage and low noise output make it ideal for low power applications.
