DESCRIPTIONThe REG102 is a family of low-noise, low-dropout linear
regulators with low ground pin current. The new DMOS
topology provides significant improvement over previous
designs, including low-dropout voltage (only 150mV typ at
full load), and better transient performance. In addition, no
output capacitor is required for stability, unlike conventional
low-dropout regulators that are difficult to compensate and
require expensive low ESR capacitors greater than 1μF.
Typical ground pin current is only 600μA (at IOUT = 250mA)
and drops to 10nA when not enabled. Unlike regulators with
PNP pass devices, quiescent current remains relatively con-
stant over load variations and under dropout conditions.
The REG102 has very low output noise (typically 28μVrms
for VOUT = 3.3V with CNR = 0.01μF), making it ideal for use
in portable communications equipment. On-chip trimming
results in high output voltage accuracy. Accuracy is main-
tained over temperature, line, and load variations. Key pa-
rameters are tested over the specified temperature range
(–40°C to +85°C).
The REG102 is well protected—internal circuitry provides a
current limit that protects the load from damage; furthermore,
thermal protection circuitry keeps the chip from being dam-
aged by excessive temperature. The REG102 is available in
SOT23-5, SOT223-5, and SO-8 packages.
