DESCRIPTION

The SP6203/6205 are ultra low noise CMOS LDOs with very low dropout and ground current. The noise performance is achieved by means of an external bypass capacitor without sacrificing turn-on and turn-off speed critical to portable applications. Extremely stable and easy to use, these devices offer excellent PSRR and Line/Load regulation. Target applications include battery-powered equipment such as portable and wireless products. Regulators' ground current increases only slightly in dropout. Fast turn-on/turn-off enable control and an internal 30 pull down on output allows quick discharge of output even under no load conditions. Both LDOs are protected with current limit and thermal shutdown. Both LDO's are availiable in fixed & adjustable output voltage versions and come in an industry standard SOT-23 5-pin package. For SC-70 100mA CMOS LDO, SP6213 is available.

Note 1: The maximum allowable power dissipation depends on the ambient temperature and can be calculated using the formula: PD = (TJ(max) - TA) / JA, where TJ(max) is the junction temperature, TA is the ambient temperature and JA is the junction-to-ambient thermal resistance. Exceeding the maximum allowable power dissipation will result in excessive die temperature and the regulator will go into thermal shutdown. For is 256C/W, mounted a PC board with minimum copper area. Note 2: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 3: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Note 4: Dropout-voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the ground pin current. Note 6: Output noise voltage is defined within a certain bandwidth, namely 100kHz. An external bypass cap (10nF) from reference output (BYP pin) to ground significantly reduces noise at output. Note 7: Thermal regulation is defined as the change in output voltage at a time "t" after a change in power dissipation is applied, excluding load and line regulation effects. Specifications are for a 300mA load pulse at VIN = 6V for = 1ms. Note 8: The wake-up time (TWU) is defined as the time it takes for the output to start rising after enable is brought high. Note 9: The total turn-on time is called the settling time (TS), which is defined as the condition when both the output and the bypass node are within 2% of their fully enabled values when released from shutdown. Note 10: For output voltage versions requiring VIN to be lower than 4V, timing (TON & TOFF) increases slightly.
