GM6355
300mA LOW NOISE CMOS LDO
WITH ENABLE FUNCTION
Description
Maximum output current: 300mA
The GM6355 series is a low-dropout linear
regulator. It is designed specifically for battery-
operated systems with the ground current as low
as 50μA typical. This feature significantly extends
the battery life. Low power consumption and high
accuracy is achieved through CMOS and
programmable fuse technologies.
Minimum output voltage as low as
0.9V
High output voltage accuracy: ± 1.5%
Low power consumption
On chip thermal and short circuit
protections
GM6355 offers adjustable output option with VREF
= 0.9V as well fixed output voltages including from
0.9V to 6.0V with 0.1V increment.
Low dropout voltage – 300mV @
300mA
Minimum input voltage 2.0V
GM6355 consists of a high-precision voltage
reference, an error correction circuit, and a
current limited output driver. With good transient
responses, output remains stable even during
load changes.
ꢀ
With its high ripple rejection ratios, this series can
be used with power supply noise. A 470pF
capacitor from the bypass (BY) input to ground
reduces noise presenting on the internal
reference, which in turn significantly reduces
output noise. If output noise is not a concern, this
input may be left unconnected. However, to use
larger capacitor values Cbp it will result in a longer
time to rated output voltage when power is initially
applied.
GM6355 incorporates both over-temperature and
over-current protection. SOT23-5 (300mW)
packages is available.
