DIO8018

7-Channel LDO PMIC for Camera Applications

Features

Descriptions



LDO1 and LDO2:

The DIO8018 is a PMIC with 7 integrated LDOs.

- input voltage: 0.6 V ~ 2.0 V

- output current: 1500 mA

- output voltage:

The PMIC has 2 low dropout LDOs for high

current DVDD and

5 high PSRR LDOs for

noise-sensitive power rails. The DIO8018 has 5

independent input pins for individual LDOs; VIN12

is for LDO1 and LDO2; VIN34 is for LDO3 and

LDO4; VIN5 for LDO5, VIN6 for LDO6 and VIN7 for

LDO7. The DIO8018 has a separate system input,

VSYS, which is the bias pin for the LDOs.

0.504 V ~ 1.504 V at 8 mV/step

- dropout: 120 mV at 1.2 V, 1500 mA output

- ±0.5% (typ) accuracy

LDO3, LDO4 and LDO6

- input voltage: 1.8 V ~ 5.5 V

- output current: 300 mA

- output voltage:

The output voltage and power-up sequence of

LDOs can be set through the I²C interface. The

DIO8018 also integrates the fault monitoring

features with interrupt indication.

The 7-bit I²C address of the device is 011 0101 by

default but can be reprogrammed so that multiple

devices can be connected to the same I²C bus.

The DIO8018 is available in 1.61 mm × 1.96 mm,

20-ball WLCSP package. The device is Pb-free

and halogen-free.

1.500 V ~ 3.412 V at 8 mV/step

- dropout: 100 mV at 2.8 V, 300 mA

- ±0.5% (typ) accuracy

LDO5 and LDO7

- input voltage: 1.8 V ~ 5.5 V

- output current: 600 mA

- output voltage:

1.500 V ~ 3.412 V at 8 mV/step

- dropout: 135 mV at 2.8 V, 600 mA

- ±0.5% (typ) accuracy
