3 / 11 page CAT6221 © Catalyst Semiconductor, Inc. 3 Doc. No. MD-10001 Rev. A Characteristics subject to change without notice ELECTRICAL OPERATING CHARACTERISTICS (1) VIN = VOUT + 1.0V, VEN = High, IOUT = 100µA, CIN = COUT = 1µF, ambient temperature of 25ºC (over recommended operating conditions unless specified otherwise). Bold numbers apply for the entire junction temperature range. Symbol Parameter Conditions Min Typ Max Unit -1.0 +1.0 VOUT-ACC Output Voltage Accuracy Initial accuracy -2.0 +2.0 % TCOUT Output Voltage Temp.

Notes: (1) Specification for 2.8V output version unless specified otherwise. (2) Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. During test, the input voltage stays always above the minimum 2.3V. (3) Specification for 1.8V output version. |
