Description
The TPL730 series products are high performance and low
dropout linear regulators. The TPL730 series products support
maximum 300 mA output current with low quiescent current and
high PSRR. The TPL730 series products is stable with ceramic
output capacitor from 2.2 μF to 10 μF.
The TPL730 series products have a high PSRR with 60 dB at 1
KHz. This feature makes TPL730 series products very suitable
for power-sensitive applications with high noise from previous
stage power supply. As low as 49 μA quiescent current and only
20 nA shutdown current makes the TPL730 series products
ideal choices for portable devices with battery power supply.
Current-limit foldback and thermal overload protection circuits
improves the reliability under heavy load conditions.
The TPL730 series products provide several output voltage
version options including fixed version and adjustable version
with ±2% output voltage accuracy over operating conditions.
The TPL730 series products are guaranteed over operating
temperature range from –40°C to +85°C.
Maximum Output Current: 300 mA
Low Dropout Voltage: 200 mV at 300 mA
Low Quiescent Current and Shutdown Current
Foldback Current Limit and Thermal Protection
Stable with 2.2 μF Ceramic Capacitor
Soft-start Limits Input Current Surge During Enable
Thermal Shutdown Protection
Operating Temperature Range: −40°C to +85°C
Junction Temperature Range: −40°C to +125°C
Package options: SOT23-5, SC70-5, 1×1 DFN-4

Input voltage pin. Bypass IN to GND with a 1 μF or greater capacitor.
Regulated output voltage pin. Bypass OUT to GND with a 2.2 μF or greater capacitor.
Regulator enable pin. Drive EN high to turn on the regulator; drive EN low to turn off the regulator.
For automatic startup, connect EN to IN directly.
Ground reference pin. Connect GND pin to PCB ground plane directly.
No connection.
Output feedback pin (Adjustable version only). Connect to a resistor divider to adjust the output
voltage.
