DESCRIPTION
The SP6222 and SP6223 are CMOS LDOs designed to meet a broad range of applications that require accuracy,
speed and ease of use. These LDOs offer extremely low quiescent current which only increases slightly under load,
thus providing advantages in ground current performance over bipolar LDOs. The LDOs handle an extremely wide
load range and guarantee stability with a 1μF ceramic output capacitor. They have excellent low frequency PSRR,
not found in other CMOS LDOs and thus offer exceptional Line Regulation. High frequency PSRR is 55dB (typical)
at 1kHz. Load Regulation is excellent and temperature stability is comparable to bipolar LDOs. An enable feature
is provided on all versions. The SP6222/6223 is available in fixed and adjustable output voltage versions in
industry standard SC70 and SOT23 packages.

Note 1. The maximum allowable power dissipation at any TA (ambient temperature) is PD (MAX) = (TJ (MAX) TA) /
θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and
the regulator will go into thermal shutdown. The θJA of the SP6222/23 (SC-70-5) is 330°C/W mounted
on a PC board with minimum copper area (see “Thermal Considerations” section for further details).
Note 2. Minimum VIN must meet 2 conditions: VIN >1.6V and VIN > {VOUT + DOV}
Note 3. Dropout Voltage DOV is defined as the input to output differential at which the output voltage drops
2% below its nominal value measured at 1V differential. The DOV specification is not applicable to
output voltages less than 2.7V.
