1.5A Very L.D.O Voltage Regulator
LM29150/1/2/3
[ Note. ]
1. Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle(≤1%).
The maximum continuous supply voltage is 26V
2. Full load current(IFL ) is defined as 1.5A
3. Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal
value with Vout to Vin
4. Vin = Vout(nominal) +1V. For example, use Vin =4.3V for a 3.3V regulator or use 6V for a 5V regulator.
Employ pulse-testing procedures to minimize temperature rise.
5. Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the
load current plus the ground pin current.
6. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
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 or line regulation effects. Specifications are for a 200mA load pulse at Vin= 20V (a 4W
pulse) for T= 10ms
8. Vref ≤ Vout ≤ (Vin -1V), 2.3V ≤ Vin ≤ 26V, 10mA＜IL IFL, TJ＜ TJ Max
9. Comparator thresholds are expressed in terms of a voltage differential at the Adjust terminal below the nominal
reference voltage measured at. 6V input. To express these thresholds in terms of output voltage change,
multiply by the error amplifier gain = Vout/Vref = (R1 +R2)/R2. For example, at a programmed output voltage of
5V, the Error output is guaranteed to go low when the output drops by 95mV x 5V/ 1.240V - 384mV.
Thresholds remain constant as a percent of Vout as Vout is varied, with the dropout warining occurring at
typically 5% below nominal, 7.7% guaranteed.
10. Ven ≤ 0.8V and Vin≤26V, Vout=0
11. When used in dual supply system where the regulator load is returned to a negative supply, the output
Voltage must be diode clamped to ground.
