CAT803 Datasheet, PDF (4/14 Pages) Catalyst Semiconductor – 3-Pin Microprocessor Power Supply Supervisors

CAT803, CAT809, CAT810
Electrical CHARACTERISTICS (continued)
V_CC = Full range, T_A = -40ºC to +85ºC unless otherwise noted. Typical values at T_A = +25ºC and V_CC = 5V for
L/M/J versions, V_CC = 3.3V for T/S versions, V_CC = 3V for R version and V_CC = 2.5V for Z version.
