AEC-Q100 36V Input / 300mA High-Speed Voltage Regulators

Torex Semiconductor Ltd. has launched the XD6702 as a new series of AEC-Q100 (Grade 2) compliant voltage regulators. The XD6702 series are CMOS high-speed voltage regulator ICs with a 36V input and low supply current. The output voltage is fixed internally by laser trimming and can be set from 1.8V to 18.0V in 0.1V steps. (standard voltage include: 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 5.0V, 8.0V).

The over-current protection circuit and overheat protection circuit are built-in. The protection circuits activate when output current or junction temperature reaches the limiting current or temperature.

The soft start circuit limits the rush current that flows from VIN to VOUT when the IC starts, enabling a stable startup sequence. The IC is put in the standby state by inputting L level into the CE pin, and the supply current is reduced to 0.1µA. A low-ESR capacitor such as a ceramic capacitor can also be used for CL.

Output voltages will vary as a result of changes in load current or fluctuations in input voltage. Changes in output voltage could cause malfunctions or other problems in devices at later stages, so such changes must be kept to a minimum. To do so, load-transient responsiveness is important for responding to changes in load current. The XD6702 series have quiescent currents which are smaller than those of conventional bipolar regulators and also exhibit high-speed responsiveness.

The package is high-density mounting type SOT-89-5.
