RF Linear Regulators
GENERAL DESCRIPTION
FEATURES
The SGM2036 series low-power, low-dropout, CMOS
Low Dropout Voltage
linear voltage regulators operate from a 1.6V to 5.5V
Thermal Overload Protection
input voltage and deliver up to 300mA output current.
Built-In Fold Back Protection Circuit
They are the perfect choice for low voltage, low power
20μA Low Supply Current
applications. A low ground current makes this part
10nA Logic-Controlled Shutdown
attractive for battery operated power systems. The
1.6V to 5.5V Input Voltage Range
SGM2036 series also offer low dropout voltage to
Fixed Outputs of 0.8V, 0.9V, 1.0V, 1.05V, 1.1V, 1.2V,
prolong battery life in portable electronics. Systems
1.3V, 1.35V, 1.5V, 1.8V, 1.85V, 2.1V, 2.2V, 2.3V,
requiring a quiet voltage source, such as RF
2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 2.9V, 3.0V, 3.1V,
applications, will benefit from the SGM2036 series’ low
3.3V, 3.6V, 4.2V, 4.4V and 5.0V
output noise and high PSRR.
Adjustable Output from 0.8V to 5.0V
Short Auto-Discharge Function
Other
features
include
a

ESD SENSITIVITY CAUTION
This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. SGMICRO recommends that
all integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation
procedures can cause damage. ESD damage can range from
subtle performance degradation to complete device failure.
Precision integrated circuits may be more susceptible to
damage because very small parametric changes could cause
the device not to meet its published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, specification or other related things if
necessary without notice at any time.

FUNCTION
Enable Pin. This pin has an internal pull-down resistor. A logic low
reduces the supply current to less than 1μA. Connect to IN for
normal operation.
Regulator Input. Supply voltage can range from 1.6V to 5.5V.
Bypass with a 1μF capacitor to GND.
Reference-Noise Bypass Pin (fixed voltage version only). Bypass
with a low-leakage 0.01μF ceramic capacitor for reduced noise at
the output. The capacitor is recommended to be placed very close
to the pin for high PSRR.
Feedback Pin (adjustable voltage version only). This is used to set
the output voltage of the device.
The exposed pad should be connected to a large ground plane to
maximize thermal performance.

NOTES:
1. Maximum output current is affected by the PCB layout, size of metal trace, the thermal conduction path between metal layers,
ambient temperature and the other environment factors of system. Attention should be paid to the dropout voltage when VIN <
VOUT + VDROP.
2. The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V or 2.5V.
3. Time needed for VOUT to reach 90% of final value.

APPLICATION NOTE
When LDO is used in handheld products, attention
must be paid to voltage spikes which could damage
SGM2036. In such applications, voltage spikes will be
generated at charger interface and VBUS pin of USB
interface when charger adapters and USB equipments
are hot-plugged. Besides this, handheld products will
be tested on the production line without battery. Test
engineer will apply power from the connector pin which
connects with positive pole of the battery. When
external power supply is turned on suddenly, the
VCC
Input
BZM55B5V6

1μF
IN
voltage spikes will be generated at the battery
connector. The voltage spikes will be very high, and it
always exceeds the absolute maximum input voltage
(6.0V) of LDO. In order to get robust design, design
engineer needs to clear up this voltage spike. Zener
diode is a cheap and effective solution to eliminate
such voltage spike. For example, BZM55B5V6 is a
5.6V small package Zener diode which can be used to
remove voltage spikes in cell phone designs. The
schematic is shown below.
