The 88PG8318 is a high performance general purpose
power management regulator housed in a 3mm x 4mm
DFN-12 package with multiple outputs to power I/O, analog,
and core voltage for DSP or CPU applications. It includes
one switching regulator and two Low Dropout (LDO)
regulators. The switching regulator utilizes a proprietary
internally compensated PWM control to regulate the output
voltage, which offers fast transient response and minimal
external components. The 88PG8318 operates from 2.7V to
5.5V input voltage range. The step-down switching regulator
can deliver up to 1.2A output current while each LDO is

The switching regulator output voltage can be set to one of
eight standard voltages through the VSET resistor. The
step-down regulator can also be programmed from 0.72V to
3.63V through the EN/SDI input. The switching frequency is
2MHz (typical), allowing the use of low profile surface
mounted inductors and low value capacitors.
Features
Input quiescent currents of the 88PG8318 at no loads is
85µA (typical), resulting in high efficiencies at both light and
full loads.

88PG839
The 88PG839 is a high performance, hysteretic step-down
switching regulator that utilizes a proprietary, internally
compensated Pulse Width Modulation (PWM) control to
regulate the output voltage. The regulator offers fast
transient response time and requires no external
compensation. The device operates from an input voltage
range of 2.7V to 5.5V and delivers up to 2A DC output
current. The switching frequency is typically 2MHz, allowing
the use of low profile surface mounted inductors and low
value ceramic capacitors.
Features
The step-down regulator includes the ability to easily
program the output voltage with external resistors. The
output voltage range is 0.64V to 3.63V. The output voltage
can be changed On-the-Fly (OTF) from a nominal value by
a percentage through connecting the OTF pin to a high
level, making it ideal for portable applications.

88PG877
The 88PG877 is an intelligent digital synchronous
step-down (buck) switching regulator housed in a 3mm x
4mm QFN-18 package. Internally self-compensated, these
step-down regulators require no external compensation and
work with low-ESR output capacitors to simplify the design,
minimize board space, and reduce the amount of external
components. The switching frequency for the step-down
regulator is 1MHz, allowing the use of low profile surface
mount inductors and low value capacitors. The step-down
regulator includes programmable output voltage to provide
the user the ability to easily set the output voltage with
external resistors, logic control, or serial data interface. The
output voltage range is 0.72V to 3.63V.
Other key features of the 88PG877 include soft start, an
internal current limit, an under voltage lockout, thermal
shutdown, over voltage protection, and a power good (PG)
signal.
Features

Low quiescent current
Stable with ceramic output capacitors
No external compensation required
Up to 95% efficiency
Peak switch current limit up to 7.5A
Input voltage range: 3.0V to 5.5V

88PH845
The 88PH845 device is a simple, easy to use high-voltage
synchronous buck switching regulator. A digital control
algorithm provides a fast transient response and requires no
external compensation components, minimizing the external
component count. The output voltage of the Marvell®
regulator can be set with external resistors (one allows a
minor range of settings, while two are used to achieve a full
range of program settings), logic programmability, or a serial
interface. The input voltage range is 4.5V to 15.7V. The
output voltage range is 0.9V to 5.5V.
The step-down regulator is internally self-compensated and
requires no external compensation. The regulator works
with low-ESR output capacitors to simplify the design,
minimize board space, and reduce the amount of external
components. The switching frequency for the step-down
regulator is 500kHz, allowing the use of low profile surface
mount inductors and low value capacitors.
