FAN53870UC00X

The FAN53870UC00X from On Semiconductor is a versatile Power Management IC (PMIC) tailored for mobile power applications, particularly camera modules. This device integrates multiple Low Dropout Regulators (LDOs), including two high-power LDOs capable of operating with an input as low as 1.0 V, and three LDOs designed for ultra-low noise and high PSRR for sensitive analog/RF circuits. Additionally, it features two general-purpose LDOs for excellent overall performance.

The PMIC supports programmable output voltages ranging from 0.8 V to 1.5 V for LDO1/LDO2 and 1.5 V to 3.4 V for other LDOs, with output current capabilities of up to 1.2 A. It operates with an input voltage range of 1.0 V to 2.0 V for LDO1/LDO2 and 1.9 V to 5.5 V for the others, with guaranteed operation down to 2.5 V battery voltage. Key features include soft-start, programmable power sequencing, current limit, and I2C serial control for voltage and feature programming.

Designed for compact applications, the FAN53870UC00X is available in a small footprint 20-bump WLCSP package measuring 1.61 x 1.96 mm with a 0.35 mm pitch. Its robust protection features, including thermal shutdown, under-voltage lockout, and over-current protection, ensure reliable operation in demanding environments.

This PMIC is well-suited for applications such as smartphones, wearables, smartwatches, health monitoring devices, sensor drives, and RF modules where efficient and stable power management is critical.
