SGM2032
Low Power, Low Dropout,
RF Linear Regulators
GENERAL DESCRIPTION
FEATURES
The SGM2032 series low-power, low-noise, low-dropout,
CMOS linear voltage regulators operate from a 2.5V to
5.5V input voltage. They are the perfect choice for low
voltage, low power applications. A low ground current
makes this part attractive for battery operated power
systems. The SGM2032 series also offer low dropout
voltage to prolong battery life in portable electronics.
Systems requiring a quiet voltage source, such as RF
applications, will benefit from the SGM2032 series’ ultra
low output noise and high PSRR. An external noise
bypass capacitor connected to the device’s BP pin can
further reduce the noise level.

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.
NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the latest datasheet.

APPLICATION NOTE
When LDO is used in handheld products, attention must be paid to voltage spikes which could damage SGM2032. 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 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.
