The LDOs handle an extremely wide load range and guarantee stability with a 1μF ceramic output capacitor. They have excellent low frequency Power Supply Rejection Ratio (PSRR), not found in other CMOS LDOs and thus offer exceptional Line Regulation. High frequency PSRR is better than 40dB up to 400kHz.

The LDO amplifier has excellent gain and thus touts PSRR performance not found in other CMOS LDOs. The amplifier guarantees no overshoot on power up or while enabled through the EN pin. The amplifier also contains an active pull down, so that when the load is removed quickly the output voltage transient is minimal; thus output deviation due to load transient is small and fairly well matched when connecting and disconnecting the load. GENERAL OVERVIEW The SP6200 and SP6201 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 better than 40dB up to 400kHz. Load Regulation is excellent and temperature stability is comparable to bipolar LDOs. Thus, overall system accuracy is maintained under all DC and AC conditions. Enable feature is provided on all versions. A Vout good indicator (RSN pin) is provided in all the fixed output voltage devices. An adjustable output version is also available. Current Limit and Thermal protection is provided internally and is well controlled. An accurate 1.250V bandgap reference is bootstrapped to the output in fixed output versions of 2.7V and higher. This increases both the low frequency and high frequency PSRR. The adjustable version also has the bandgap reference bootstrapped to the output, thus the lowest externally programmable output voltage is 2.7V. The 2.5V fixed output version has the bandgap always connected to the Vin pin. Unlike many LDOs, the bandgap reference is not brought out for filtering by the user. This tradeoff was made to maintain good PSRR at high frequency (PSRR can be degraded in a system due to switching noise coupling into this pin). Also, often leakages of the bypass capacitor or other components cause an error on this high impedance bandgap node. Thus, this tradeoff has been made with "ease of use" in mind. ARCHITECTURE The SP6200 and SP6201 are only different in their current limit threshold. The SP6200 has a current limit of 140mA, while the SP6201 current limit is 420mA. The SP6201 can provide pulsed load current of 300mA. The 12/17 Rev. 2.1.1 SP6200 / SP6201 100mA/200mA Micropower CMOS LDO Regulators PROTECTION bootstrapped to the output, the output voltage must be above the minimum bandgap supply voltage. The bandgap requires 2.7V or greater at -40°C and requires 2.5V or greater at 0°C. The regulator's output can be adjusted to a specific output voltage by using two external resistors, see block diagram. The resistor's set the output voltage based on the following equation: Current limit behavior is very well controlled, providing less than 10% variation in the current limit threshold over the entire temperature range for both SP6200 and SP6201. The SP6200 has a current limit of 140mA, while the SP6201 has a current limit of 420mA. Thermal shutdown activates at 162°C and deactivates at 147°C. Thermal shutdown is very repeatable with only a 2 to 3 degree variation from device to device. Thermal shutdown changes by only 1 to 2 degrees with Vin change from 4V to 7V. 𝑉𝑉𝑂𝑂𝑂𝑂𝑂𝑂 = 1.25 × �1 + 𝑅𝑅2 � 𝑅𝑅1 Resistor values are not critical because the ADJ node has a high input impedance, but for best results use resistors of 470kΩ or less. A capacitor from ADJ to VOUT pin provides improved noise performance as is shown in the following plot. ENABLE (SHUTDOWN NOT) INPUT The LDOs are turned off by pulling the EN pin low and turned on by pulling it high. If it is not necessary to shut down the LDO, the EN (pin 3) should be tied to IN (pin 1) to keep the regulator output on at all time. The enable threshold is 0.9V and does not change more than 100mV over the entire temperature and VIN voltage range. The lot to lot variations in Enable Threshold are also within 100mV. Shutdown current is guaranteed to be
