CS5201-1 CHERRY [Cherry Semiconductor Corporation], CS5201-1 Datasheet - Page 2

• Manufacturer Part Number: CS5201-1
• Description: 1A Adjustable Linear Regulator
• Manufacturer: CHERRY [Cherry Semiconductor Corporation]

Note 1: Load regulation and output voltage are measured at a constant junction temperature by low duty cycle pulse testing. Changes in output
Note 2: Specifications apply for an external Kelvin sense connection at a point on the output pin 1/4Ó from the bottom of the package.
Note 3: Dropout voltage is a measurement of the minimum input/output differential at full load.
Note 4: The minimum load current is the minimum current required to maintain regulation. Normally the current in the resistor divider used
Note 5: Guaranteed by design, not 100% tested in production.
Note 6: Thermal shutdown is 100% functionally tested in production.
