Texas Instruments Voltage Regulators - Linear TPS7248QP

The TPS7248QP is a low-dropout (LDO) voltage regulator from the TPS72xx family, designed for applications requiring efficient power management. It offers a fixed output voltage of 4.85 V and can deliver up to 250 mA of output current. The device features a maximum dropout voltage of less than 85 mV at 100 mA load current, ensuring minimal voltage loss. It operates with a low quiescent current of 180 µA typical, which is stable across the entire load range, making it suitable for battery-powered devices. The TPS7248QP is available in compact 8-pin SOIC and TSSOP packages, ideal for space-constrained designs. It includes a power-good (PG) status output for monitoring the output voltage and features a logic-enabled sleep mode that reduces quiescent current to a maximum of 0.5 mA. The output voltage tolerance is specified at ±2% over the full operating range, ensuring reliable performance in various conditions. This regulator is particularly well-suited for portable systems such as laptops and cellular phones, where efficiency and compactness are critical.
