10.5V Input, Low Power Consumption, High Speed 200mA LDO Regulator XC6505 Series

Mar 30, 2011

TOREX SEMICONDUCTOR LTD. (Tokyo Japan: President, Tomoyuki Fujisaka) has developed a 10.5V input, low power consumption, high-speed 200mA LDO regulator.

The XC6505 series of LDO regulators achieve load-transient response characteristics (PSRR=60dB@1kHz) on a par with high-speed LDO regulators but with the added benefit of a low power consumption of only 5.5μA.
The input voltage range is 1.7 to 10.5V, making this series ideal for specifications that require 5V supply, such as applications that operate on a Li-ion two-cell battery, four dry cell batteries, or a 9V dry cell battery, or in the latter stage of 6V output DC/DC. The maximum output current is 200mA and the output voltage range can be set in steps of 0.1V within a range of 1.5 to 8.0V. Voltage accuracy is ±1.0% (2.0 to 8.0V) or ±20mV (1.5 to 1.9V). Dropout voltage is 190mV at 100mA (VOUT=3.3V). The XC6505 series includes current limitation (300mA, TYP.), short circuit protection (110mA, TYP.), and thermal protection.
The XC6505B series includes a CL discharge function that enables high-speed return of the VOUT pin to the VSS level by quickly discharging the charge.  
The ultra small USP-6C package, SOT-25 and SOT-89-5 packages are available for selection as appropriate for the application. This is also an environment-friendly product that complies with the RoHS Directive of the EU and is Pb-free.

XC6505 Series Features

  • Supports 10.5V operation.
  • Low power consumption of 5.5μA and ripple rejection ratio of 60dB at 1kHz.
  • Stable temperature characteristics are achieved: ±30ppm/℃ (-40℃ to +105℃).
  • Low dropout: 190mV at 100mA(VOUT=3.3V).
  • The package can be selected from the USP-6C, SOT-25, or SOT-89-5 to match the application.
