Overview
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.

Power management of battery-powered electronic devices is becoming increasingly more important for the microelectronics industry. This white paper details the difference between low dropout (LDO) voltage regulators that use external output capacitors and those that do not, and how your system designs can benefit from not using an output capacitor. Well-designed capless LDO voltage regulators can have multiple benefits, and they are presented here.
There are many factors that must be considered when developing a custom System on a Chip (SoC) for Internet of Things (IoT) applications. Chief among these are the power management circuits on the die. Vidatronic offers this white paper to discuss these considerations and all of the various circuit blocks that can be found in this application. Vidatronic IP solutions are discussed and the benefits they bring to IoT SoC designers.
Power management poses challenges
Power management of battery-powered electronic devices is becoming increasingly more important for the present and future microelectronics industry. This application note details the difference between low dropout (LDO) voltage regulators that use output capacitance and those that do not and how your system designs can benefit from or be improved by not using an output capacitor.
The vast array of on-chip LDO options and characteristics can make the selection process complex.
Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as low dropout (LDO) regulators. This paper explains the fundamentals of LDOs and introduces Vidatronic’s LDO technology which solves many of the known shortcomings of LDO circuits.
