LP2987/LP2988
Micropower, 200 mA Ultra Low-Dropout Voltage
Regulator with Programmable Power-On Reset Delay;
Low Noise Version Available (LP2988)
General Description
The LP2987/8 are fixed-output 200 mA precision LDO volt-
age regulators with power-ON reset delay which can be
implemented using a single external capacitor.
The LP2988 is specifically designed for noise-critical appli-
cations. A single external capacitor connected to the Bypass
pin reduces regulator output noise.
Using an optimized VIP
(Vertically Integrated PNP) pro-
cess, these regulators deliver superior performance:
Dropout Voltage:
180 mV
@
200 mAload, and 1 mV
@
1 mA
load (typical).
Ground Pin Current:
1 mA
@
200 mA load, and 200 μA
@
10 mA load (typical).
Sleep Mode:
The LP2987/8 draws less than 2 μA quiescent
current when shutdown pin is held low.
Error Flag/Reset:
The error flag goes low when the output
drops approximately 5% below nominal. This pin also pro-
vides a power-ON reset signal if a capacitor is connected to
the DELAY pin.
Precision Output:
Standard product versions of the LP2987
and LP2988 are available with output voltages of 5.0V, 3.8V,
3.3V, 3.2V, 3.0V, or 2.8V, with guaranteed accuracy of 0.5%
(“A” grade) and 1% (standard grade) at room temperature.
