DESCRIPTION

The ST5R00 is an high efficiency VFM Step-up DC/DC converter for small, low input voltage or battery powered systems with ultra low quiescent supply current. The ST5Rxx accept a positive input voltage from start-up voltage to VOUT and convert it to a higher output voltage in the 2.5 to 5V range.

■ VERY LOW SUPPLY CURRENT

■ REGULATED OUTPUT VOLTAGE

■ WIDE RANGE OF OUTPUT VOLTAGE AVAILABLE (2.5V, 2.8V, 3.0V, 3.3V, 5.0V)

■ OUTPUT VOLTAGE ACCURACY ±5

■ OUTPUT CURRENT UP TO 100mA

■ LOW RIPPLE AND LOW NOISE

■ VERY LOW START-UP VOLTAGE

■ HIGH EFFICIENCY (VOUT = 5V TYP. 87)

■ FEW EXTERNAL COMPONENTS

■ VERY SMALL PACKAGE: SOT23-5L

ST5R28M属于集成电路（IC） > 稳压器 - DC-DC 开关稳压器。意法半导体（ST）集团制造生产的ST5R28M稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
