• Manufacturer Part Number: MAX6766
• Description: Automotive Micropower Linear Regulators with Supervisor
• Manufacturer: MAXIM [Maxim Integrated Products]

When V
bilities decline drastically. High-impedance CMOS-
logic inputs connected to RESET can drift to
undetermined voltages. This presents no problems in
most applications, since most µPs and other circuitry
do not operate with supply voltages below 1V. In those
applications where RESET must be valid down to 0V,
adding a pulldown resistor between RESET and ground
sinks any stray leakage currents, holding RESET low
(Figure 5). The value of the pulldown resistor is not criti-
cal; 100kΩ is large enough not to load RESET and
small enough to pull RESET to ground. Open-drain
RESET versions are not recommended for applications
requiring valid logic for V
