The device offers several voltage thresholds, VTH+ (see Table 8) and it is available in miniature flip chip 6-bump package. Figure 1.

Otherwise, the output is connected to ground GND. The output is current limited (see Table 5). 2.2 Enable input, EN A Logic low on the enable input disconnects the output from VIN and disables the device, which enters a standby mode with very low current consumption (see Table 5). 2.3 Inhibit input, INH A logic high on the inhibit input disconnects the output from VIN. Table 2. Truth table VCC VTH- (falling edge) EN(1) x L x H INH x x H L OUT connected to GND connected to GND connected to GND connected to VIN 1. Once the device is disabled by EN input, the VCC must be above VTH+ to reconnect output to VIN. 8/20 STM1066 Typical operating characteristics 3 Typical operating characteristics Figure 5.
