DESCRIPTION
The REG113 is a family of low-noise, low-dropout linear
regulators with low ground pin current. Its new DMOS topol-
ogy provides significant improvement over previous designs,
including low-dropout voltage (only 250mV 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 re-
quire expensive low ESR capacitors greater than 1
μ
F.
Typical ground pin current is only 850
μ
A (at I
OUT
= 400mA)
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 REG113 has very low output noise (typically 28
μ
Vrms
for V
OUT
= 3.3V with C
NR
= 0.01
μ
F), making it ideal for use
in portable communications equipment. Accuracy is main-
tained over temperature, line, and load variations. Key
parameters are tested over the specified temperature range
(–40
°
C to +85
°
C).
The REG113 is well protected—internal circuitry provides a
current limit which protects the load from damage, further-
more, thermal protection circuitry keeps the chip from being
damaged by excessive temperature. The REG113 is avail-
able in SOT23-5 and MSOP-8 packages.
