LD1117
Adjustable and fixed low drop positive voltage regulator
Datasheet - production data
flows mostly into the load. Only a very common
10 µF minimum capacitor is needed for stability.
On chip trimming allows the regulator to reach a
very tight output voltage tolerance, within ± 1 % at
25 °C. The adjustable LD1117 is pin to pin
compatible with the other standard. Adjustable
voltage regulators maintaining the better
performances in terms of drop and tolerance.
• Low dropout voltage (1 V typ.)
• 2.85 V device performances are suitable for
SCSI-2 active termination
• Output current up to 800 mA
• Fixed output voltage of: 1.2 V, 1.8 V, 2.5 V,
3.3 V, 5.0 V
• Adjustable version availability (V
• Internal current and thermal limit
• Available in ± 1 % (at 25 °C) and 2 % in full
temperature range
• Supply voltage rejection: 75 dB (typ.)

Description
The LD1117 is a low drop voltage regulator able
to provide up to 800 mA of output current,
available even in adjustable version (V
1.25 V). Concerning fixed versions, are offered
the following output voltages: 1.2 V, 1.8 V, 2.5 V,
2.85 V, 3.3 V and 5.0 V. The device is supplied in:
SOT-223, DPAK, SO-8 and TO-220. The SOT223 and DPAK surface mount packages optimize
the thermal characteristics even offering a
relevant space saving effect. High efficiency is
assured by NPN pass transistor. In fact in this
case, unlike than PNP one, the quiescent current
