General Description

Pin Number 1 2 3 TAB Package Marking Code Name GND OUT INPUT TAB Function Ground Pin Output Voltage Input Voltage Output Voltage 37_Table03.eps Part Number IMP37-25JST IMP37-30JST IMP37-33JST IMP37-25JCM IMP37-30JCM IMP37-33JCM Package SOT-223 SOT-223 SOT-223 TO-263 TO-263 TO-263 Device Markin

Key Features

  • greatly reduced quiescent operating current. The 75µA maximum specification represents an over 100 times improvement over competitive devices. Devices are short circuit protected, and a thermal protection circuit shuts the regulator off should the junction temperature exceed 165°C. The IMP37 is available in low-profile plastic SOT-223 and TO-263 packages and are pin compatible with fixed “1117” devices. Key Features x Low Dropout Voltage.
  • 0.8V maximum at 100mA.
  • 0.95V maximum a.

IMP3 7 POWER MANAGEMENT Low Dropout Positive Voltage Regulators – 800mA – 2.5V, 3.0V and 3.3V Output The IMP37 series of Low Dropout (LDO) three-terminal voltage regulators feature guaranteed low dropout voltages at currents up to 0.8A. The IMP37 regulator family dropout voltage is guaranteed to be 0.95V or lower at 0.8A. At 100mA, the maximum dropout voltage is 0.8V. Compared with “1117” type LDOs, the IMP37 has a 20% lower dropout voltage. Three fixed output voltages are offered: 2.5V, 3.0V and 3.3V. Output voltages are factory trimmed to within 1% of the nominal value. In addition to low dropout voltages, the IMP37 family features greatly reduced quiescent operating current. The 75µA maximum specification represents an over 100 times improvement over competitive devices.
