TPL740 Series 500 mA output, High PSRR, Low-Dropout Linear Regulator Features Description  Input Voltage Range: 2.4 V to 5.5 V The TPL740 series products are high performance and low dropout linear regulators. The TPL740 series products support a maximum 500 mA output current with low quiescent current and high PSRR. The TPL740 series products are stable with ceramic output capacitor from 2.2 μF to 10 μF.  Output Voltage Options: − Fixed Voltage: 1.2 V, 1.5 V, 1.8 V, 2.5 V, 2.7 V, 2.8 V, 2.9 V, 3 V, 3.3 V − Adjustable Voltage: 0.8 V to 5 V  High Output Accuracy: − ±1% Typical Under Room Temperature − ±2% Through Operating Conditions  Maximum Output Current: 500 mA  Low Dropout Voltage: 400 mV at 500 mA  Low Quiescent Current and Shutdown Current  Foldback Current Limit and Thermal Protection  Stable with 2.2 μF Ceramic Capacitor  Inrush Input Current Limitation During Start-up  Thermal Shutdown Protection  Junction Temperature Range: −40°C to +125°C  Package options: SOT23-5, SC70-5, SOT89-3, 1×1 DFN-4 Applications The TPL740 series products have a high PSRR with 60 dB at 1 kHz. This feature makes TPL740 series products very suitable for power-sensitive applications with high noise from the previous stage power supply. As low as 49 μA quiescent current and only 20 nA shutdown current makes the TPL740 series products ideal choices for portable devices with battery power supply. Current limit foldback and thermal overload protection circuits improve the reliability under heavy load conditions. The TPL740 series products provide several output voltage version options including fixed version and adjustable version with ±2% output voltage accuracy over operating conditions. The TPL740 series products are guaranteed over the junction temperature range from –40°C to +125°C.  Handheld Devices with Battery Power Supply  POS  Video Surveillance  Wireless and IoT modules Typical Application Schematic Input VOUT VIN CIN Output Input CIN COUT R1 TPL740 ADJ TPL740 FIXED Off On EN GND Off On TPL740 Fixed Output Voltage www.3peakic.com.cn Output VOUT VIN CBP COUT FB R2 EN GND TPL740 Adjustable Output Voltage 1 / 22 Rev.A.4
