UM375xx

300mA, Micropower, VLDO Linear Regulator

UM375xxS SOT23-5

UM375xxP SOT353

General Description

The UM375xx series are VLDO (very low dropout) linear regulators designed for low power

portable applications. Typical output noise is only 170μV_RMS(UM37512) and maximum dropout is

just 200mV at the load current of 100mA.The internal P-channel MOSFET pass transistor requires

no base current, allowing the device to draw only 90μA during normal operation at the maximum

load current of 300mA.

Other features include high output voltage accuracy, under voltage lockout, stability with ultra low

ESR ceramic capacitors as small as 1μF, thermal overload protection and output current limiting.

The UM375xx series are available in a low profile SOT23-5 and SOT353 package.

Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be

impaired.

Note 2: The UM375xx is tested and specified under pulse load conditions such that T_J≈T_A. The

device is guaranteed to meet performance specifications from 0℃ to 70℃. Specifications

over the – 40℃ to 125℃ operating junction temperature range are assured by design,

characterization and correlation with statistical process controls.

Note 3: This IC includes overtemperature protection that is intended to protect the device during

momentary overload conditions. Junction temperature will exceed 125℃ when

overtemperature protection is active. Continuous operation above the specified maximum

operating junction temperature may impair device reliability.

UM375xx

Pin Function

IN (Pin 1): Power for UM375xx and Load Power is supplied to the devices through the IN pin.

The IN pin should be locally bypassed to ground if the UM375xx series are more than a few

inches away from another source of bulk capacitance. In general, the output impedance of a

battery rises with frequency, so it is usually advisable to include an input bypass capacitor in

battery-powered circuits. A capacitor in the range of 0.1μF to 1μF is usually sufficient.

GND (Pin 2): Ground and Heat Sink. Solder to a ground plane or large pad to maximize heat

dissipation.

_____________

SHDN (Pin 3): Shutdown, Active Low. This pin is used to put the UM375xx into shutdown. The

_____________

SHDN pin cannot be left floating and must be tied to the input pin if not used.

NC (Pin 4): Not Connected.

OUT (Pin 5): Voltage Regulated Output. The OUT pin supplies power to the load. A minimum

output capacitor of 1μF is required to ensure stability. Larger output capacitors may be required

for applications with large transient loads to limit peak voltage transients.
