TS1540
1A Low Dropout Voltage Regulator with Low Quiescent Current
TO-252 (DPAK)
Pin Definition: 1. Output 2. Ground 3. Input
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.
Features
Very Low Ground Current (IGND = 1mA) Excellent Line Regulation Excellent Load Regulation Very Low transient Overshoot Stable with low ESR output Capacitor (ESR = 0m) Thermal Shutdown Current Limit

-60 70 dB VIN = Vout+3V Note 1: See thermal regulation specification for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18" from the package. Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 10W. Power dissipation is determined by the input / output voltage difference and the output current. Guaranteed maximum power dissipation will not be available over the full input / output voltage range. Note 3: Quiescent current is defined as the minimum output current required to maintain the regulation. Note 4: The Output Capacitor does not have a theoretical upper limit and increasing its value will increase stability COUT=100uF or more is typical for high current regulator design.
