TRS3122E: Dual supply operation capacitor values

E. Stanley Manush

Part Number: TRS3122E

For dual-supply operation with Vcc = 3.3V and VL = 1.8V, do you recommend any capacitor selections be different than those shown in Table 1?

The charge pump does not run from V_L. Table 1 should not mention V_L.

With V_CC = 3.3 V, just use four 100 nF capacitors.

Thanks Clemens. That's what I expected.
