3A Low Dropout LDO
General Description
EM5107 is a 3A low dropout linear regulator
designed for low dropout and high current
applications. This device works with dual supplies,
a control input for the control circuitry and a power
input as low as 1.05V for providing current to
output. It features 3A output current and
ultra-low-drop output voltage as well as full
protection functions. VOUT can be as low as 0.8V.
The other features include soft start, current
limit protection, Power-On-Reset function, and
over temperature protection. The EM5107 is
available in PSOP-8 package.

Power OK Indication. POK is an open-drain output. An external pull high resistor
connected to this pin is required.
Feedback Voltage. FB is the inverting input to the error amplifier. A resistor divider
7
from the output to GND is used to set the regulation voltage as
VOUT = (1 + R1/R2) x 0.8V (V). This pin has high impedance and should be kept from
noisy source to guarantee stable operation.
Output Voltage. VOUT is power output pin. An internal pull low resistance exists
6 when the device is disabled. Minimum 10uF low ESR ceramic holding capacitor is
required at this pin for stabilizing VOUT voltage.
Input Voltage. This is the drain input to the power device that supplies current to
3 the output pin. Minimum 10uF low ESR ceramic capacitor is recommended at this
pin.
2 Enable Input. Pulling the pin below 0.3V turns the regulator off
Supply Input for Control Circuit. CNTL provides supply voltage to the control
4 circuitry and driver for the pass transistor. The driving capability of output current
is proportioned to the VCNTL.
8 Ground.
5 Non Connect.
