LxxAYW DATA SHEET www.onsemi.com Ultra Low-Noise Low 5 Dropout Voltage Regulator 1 with 1.0 V ON/OFF Control THIN SOT235 SN SUFFIX CASE 483 MC33761 PIN CONNECTIONS AND The MC33761 is an Low DropOut (LDO) regulator featuring MARKING DIAGRAM excellent noise performances. Thanks to its innovative design, the circuit reaches an impressive 40 VRMS noise level without an external bypass capacitor. Housed in a small SOT23 5 leadslike 1 5 V V out in package, it represents the ideal designers choice when space and noise are at premium. The absence of external bandgap capacitor 2 GND accelerates the response time to a wakeup signal and keeps it within 40 s (in repetitive mode), making the MC33761 as a natural 3 4 ON/OFF NC candidate for portable applications. The MC33761 also hosts a novel architecture which prevents (Top View) excessive undershoots in the presence of fast transient bursts, as in any Lxx = Device Code bursting systems. A = Assembly Location Finally, with a static line regulation better than 75 dB, it naturally Y = Year shields the downstream electronics against choppy lines.
