The TS_VR_4V00_X8 is a 4V voltage regulator capable of delivering up to 16mA. It is required for the supply of other TES IPs like TS_FS_9M70_X8,
TS_VA_LNDC_X8, and TS_CS_20uA_X8. The TS_VR_4V00_X8 operates with one supply voltage, VDDA5, VDDIO (5V typical) and one precision reference voltage VREF (2.5V).
This IP supports analog-test-bus multiplexing on the ATB1 output under control of the 5-bit address input TEST_ADR_BUS<4:0>. When TEST_ADR_BUS<4:0>= HHHHL, the TS_VR_4V00_X8 sinks a 1.2µA-internal bias-replicated current through ATB1 for off-chip measurement.
The TS_VR_4V00_X8 complies with 2kV electrostatic discharges on its analog terminals VDDA4 and ATB1.
The minimum continuous operation lifetime spans 100000 hours.
