The bandgap voltage is typically 1.22 V. The EN terminal is an input which enables or shuts down the device. If EN is a low voltage level (<0.7 V), the device will be in shutdown or sleep mode. When EN goes to a high voltage level (>2 V), the device will be enabled. FB is an input terminal used for the adjustable-output option and must be connected to the output terminal either directly, in order to generate the minimum output voltage of 1.22 V, or through an external feedback resistor divider for other output voltages. The FB connection should be as short as possible. It is essential to route it in such a way to minimize/avoid noise pickup. Adding RC networks between FB terminal and VO to filter noise is not recommended because it may cause the regulator to oscillate. The VIN terminal is an input to the regulator. The VOUTPUT terminal is an output from the regulator. over operating junction temperature range (unless otherwise noted)(1)(2) UNIT Input voltage range, VI -0.3 V to 6 V Voltage range at EN -0.3 V to 6 V Peak output current Internally limited Continuous total power dissipation See Dissipation Rating Table Output voltage, VO (OUTPUT, FB) 5.5 V Operating junction temperature range, TJ -40 °C to 150°C Storage temperature range, Tstg -65 °C to 150°C ESD rating, HBM 2 kV ESD rating, CDM 500 V (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network terminal ground. PACKAGE RΘJC(°C/W) RΘJA(°C/W) (1) TO-220 2 58.7(2) TO-263 2 38.7(3) (1) For both packages, the RΘJAvalues were computed using JEDEC high K board (2S2P) with 1 ounce internal copper plane and ground plane. There was no air flow across the packages. (2) RΘJA was computed assuming a vertical, free standing TO-220 package with pins soldered to the board. There is no heatsink attached to the package. (3) RΘJA was computed assuming a horizontally mounted TO-263 package with pins soldered to the board. There is no copper pad underneath the package. 4 |
