TS1540

1A Low Dropout Voltage Regulator

with Low Quiescent Current

1/4

Version: A07

TO-252

(DPAK)

General Description

TS1540 of high current LDOs has been developed for portable application where low quiescent current is an important

requirement. The device features excellent line and load transient response which does not exceed 10% of nominal

output value for full operating temperature range even during power ON cycle and short circuit removal. Internally

trimmed, temperature compensated bandgap reference guarantees 2.5% accuracy for full range of input voltage, output

current and temperature. Included on the chip are accurate current limit and thermal shutdown protection. Device

stability is achieved with only two external low ESR ceramic capacitors.
