Description
The TPL6305 is a 3-A high-current, 1.4-V low-input
voltage linear regulator with only 300-mV maximum ultra-
low-dropout voltage at full-load condition. The TPL6305
supports adjustable output voltage ranging from 0.5 V to
5.2 V with an external resistor divider.
Inherent Output Soft Start Control
Excellent Transient Response
High PSRR:
63 dB at 1 kHz
–
–
Low-input voltage and ultra-low-dropout voltage make the
TPL6305 the ideal power supply for applications requiring
output voltage very close to the input voltage.
35 dB at 100 kHz
24-μVRMS Output Voltage Noise (100 Hz to 100 kHz)
Stable with a 10-μF Ceramic Output Capacitor
Protection:
•
•
•
The TPL6305 integrates an enable control function and
provides a very low standby power dissipation. The
TPL6305 also provides output soft-start control and
excellent transient response.
Over-Current Protection
