1 AMP ADJUSTABLE LOW VOLTAGE INPUT

INTEGRATED SWITCHING REGULATOR

• Low Voltage Input (7V)

• 89% Efficiency

• Adjustable Output Voltage

• Internal Short Circuit Protection

• Over-Temperature Protection

• On/Off Control (Ground Off)

Regulators (ISRs). These ISRs are de-

signed with premium low threshold FETs

for those applications requiring very low

input/output voltage differentials such as

battery powered equipment. This high-

performance ISR family offers a unique

combination of features combining 89%

typical efficiency with open-collector on/

off control and adjustable output voltage.

Quiescent current in the shutdown mode

is less than 100µA.

The PT6120 series is a low volt-

age input (typically 7V) version of

Power Trends’ high-performance

* ISR will operate down to no load with reduced specifications.

** Input voltage cannot exceed 30V when the inhibit function is used.

***See Thermal Derating chart.

Note: The PT6120 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.
