Ultra Low Dropout Voltage: 230mV typ at 1A and 3.3V OutputOutput Capacitor NOT Required for Stability
PORTABLE COMMUNICATION DEVICES
The REG104 is a family of low-noise, low-dropout linear
regulators with low ground pin current. Its new DMOS topology
provides significant improvement over previous designs,
including low dropout voltage (only 230mV 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 1 F.
Typical ground pin current is only 1.7mA (at IOUT = 1A) and
drops to 0.5 A in not enabled mode. Unlike regulators with
PNP pass devices, quiescent current remains relatively constant
over load variations and under dropout conditions.
The REG104 has very low output noise (typically 33 VRMS
for VOUT = 3.3V with CNR = 0.01 F), making it ideal for use
in portable communications equipment. On-chip trimming
results in high output voltage accuracy. Accuracy is maintained
over temperature, line, and load variations. Key parameters
are tested over the specified temperature range
The REG104 is well protected internal circuitry provides a
current limit which protects the load from damage. Thermal
protection circuitry keeps the chip from being damaged by
