• Manufacturer Part Number: SP6203
• Description: Low Noise / 300mA and 500mA CMOS LDO Regulators
• Manufacturer: Sipex

Note 1: Maximum power dissipation can be calculated using the formula: P
the junction temperature, T
is 6ºC/W for this package. Exceeding the maximum allowable power dissipation will result in excessive die
temperature and thermal shutdown protection. For 5 Pin SOT-23 θ
part mounted on a PC board will deliver improved thermal perfformance based on copper surface 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 10Hz < BW < 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 V
Note 8: The wake-up time (T
high.
Note 9: The total turn-on time is called the settling time (T
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 (T
