Overview
The TPS51206DSQR is a sink and source double data rate (DDR) termination regulator with a VTTREF buffered reference output, designed by Texas Instruments. This device is specifically tailored for systems that require low input voltage, low cost, and minimal external component count, where space is a critical factor. It supports all power requirements for DDR2, DDR3, Low-Power DDR3 (DDR3L), and DDR4 VTT buses. The TPS51206 maintains fast transient response and requires only a 10-µF ceramic output capacitor. It is available in a 10-pin, 2 mm × 2 mm SON (DSQ) PowerPAD™ package and operates over a temperature range of –40°C to 105°C.
