General Description
EM5102A is a 2A 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
1.2V for providing current to output. It features 2A output current and ultra-low-drop output voltage as
well as full protection functions. VOUT can be as low as 0.8V.

Pin Function
POK

VIN
CNTL
1
Power OK Indication. POK is an open-drain output. An external pull high resistor
connected to this pin is required.
2 Enable Input. Pulling the pin below 0.4V turns the regulator off
3 Input Voltage. This is the drain input to the power device that supplies current to
the output pin. VIN cannot be forced higher than VCNTL.
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. For the device to regulate, the voltage on this pin must
be at least 2.0V greater than the output voltage, and no less than VCNTL_MIN.
NC 5 No Connection inside chip.
VOUT
FB
Output Voltage. VOUT is power output pin. An internal pull low resistance exists
6 when the device is disabled. Minimum 10μF low ESR ceramic holding capacitor is
required at this pin for stabilizing VOUT voltage.
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) × 0.8V (V). This pin has high impedance and should be kept from
noisy source to guarantee stable operation.
GND
8 Ground.
