Overvoltage Protection for 2-Series, 3-Series and 4-Series Li-Ion Batteries 8-WSON -40 to 110

This family of low quiescent current low-drain (LDO) linear regulators was originally designed for handheld communication equipment and portable battery-powered applications, and can also be used in automotive applications requiring ultra-low quiescent current. Since this product has no protection against high input transient voltages inherent in automotive battery operation, it should be used as a post-regulator. This family features an ultra-low quiescent current of 2.5µA, and an enable pin that reduces current consumption to 0.1µA typical. Each device includes a voltage reference unit, error amplifier, PMOS power transistor, resistors to set the output voltage, and protection features such as current limit and temperature limit circuits. The NCV662 LDO linear regulator is designed to use low cost ceramic capacitors and requires a minimum output capacitor of 0.1 µF. The device features a tiny SC82-AB surface mount encapsulation. Lead-free plating options available. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.3 and 5.0 V.

FAN255 Low Voltage CMOS LDO features fixed or adjustable output voltage, 180mA load current, delayed power good output (open drain), and 1% output accuracy with excellent line and load regulation. External bypass capacitors provide extremely low noise operation. The FAN2558 low-voltage LDO integrates high-temperature shutdown and short-circuit protection. Outputs are stable with 1µF, low-ESR capacitors. FAN2558 is available in 5-lead SOT-23, 6-lead SOT-23 and 2X2mm MLP-6 encapsulation. FAN2558: Fixed output LDO with power good detection output FAN2558ADJ: Adjustable output LDO with power good detection output Available standard output voltages are 1.0, 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 3.3V, 3.5V , 3.6V and 3.8V. Custom output voltage options are also available.
