The TPL820 is a series of high-performance and low-dropout linear regulators. The TPL820 series supports a maximum 42-V input voltage and a 180-mA output current with low quiescent current and high PSRR. The TPL820series is stable with a 2.2-μF to 22-μF output capacitor，and a 4.7-μF ceramic capacitor is recommended.

BL1117 is a series of low dropout three-termina! regulators with a dropout of 1.3V at 1A load current. BL1117 features a very low standby current 2mA compared to 5mA of competitor.

BL8531 series are CMOS-based PFM step-up DCDC Converter. The converter can start up by supply voltage as low as 0.8V, and capable of delivering maximum 200mA output current at 3.3V output with 1.8V input Voltage. Quiescent current drawn from power source is as low as 5.5uA. All of these features make BL8531 series be suitable for the portable devices, which are supplied by a single battery to four-cell batteries.

The BL9366 is a monolithic, step-down, switch mode converter with a built-in power MOSFET. It achieves a 0.6A peak-output current over input supply 5.0V-60V with excellent load and line regulation. Current-mode operation provides a fast transient response and eases loop stabilization. Fault condition protections include cycle-by-cycle current limiting and thermal shutdown.
