NCV8154
Dual 300 mA, Low IQ, Low
Dropout, Dual Input Voltage
Regulator
The NCV8154 is 300 mA, Dual Output Linear Voltage Regulator
that offers two independent input pins and provides a very stable and
accurate voltage with ultra low noise and very high Power Supply
Rejection Ratio (PSRR) suitable for RF applications. The NCV8154 is
suitable for powering RF blocks of automotive infotainment systems
and other power sensitive device. Due to low power consumption the
NCV8154 offers high efficiency and low thermal dissipation.
Features
Operating Input Voltage Range: 1.9 V to 5.25 V
Two Independent Input Voltage Pins
Two Independent Output Voltage (for detail please refer to Ordering
Information)
Low IQ of typ. 55 mA per Channel
High PSRR: 75 dB at 1 kHz
Very Low Dropout: 140 mV Typical at 300 mA
Thermal Shutdown and Current Limit Protections

Table 1. PIN FUNCTION DESCRIPTION
Pin No. Pin Name
Description
1
GND
Power supply ground. Soldered to the copper plane allows for effective heat dissipation.
2
OUT1
Regulated output voltage of the first channel. A small 1 mF ceramic capacitor is needed from this pin to
ground to assure stability.
3
OUT2
Regulated output voltage of the second channel. A small 1 mF ceramic capacitor is needed from this pin to
ground to assure stability.
4
GND
Power supply ground. Soldered to the copper plane allows for effective heat dissipation.
5,6 N/C Not connected, can be tied to ground plane to improve thermal dissipation.
7 EN2 Driving EN2 over 0.9 V turns-on OUT2. Driving EN below 0.4 V turns-off the OUT2 and activates the active
discharge.
8 IN2 Inputs pin for second channel. It is recommended to connect 1 mF ceramic capacitor close to the device pin.
9 IN1 Inputs pin for first channel. It is recommended to connect 1 mF ceramic capacitor close to the device pin.
10 EN1 Driving EN1 over 0.9 V turns-on OUT1. Driving EN below 0.4 V turns-off the OUT1 and activates the active
discharge.
EXP
Exposed pad must be tied to ground. Soldered to the copper plane allows for effective thermal dissipation.
