LTC2802IDE#PBF from Analog Devices, in a DFN-12-EP(3x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	RIN	input	RS-232 receiver input with an internal 5kΩ termination resistor, tolerant to ±25V per absolute maximum ratings.
2	TOUT	output	RS-232 driver output, protected against overload and shorts to ground or up to ±15V.
3	VCC	power_in	Input supply of 1.8V to 5.5V, to be bypassed to GND with a 1µF capacitor.
4	VDD	power_out	Generated positive supply for the RS-232 driver (7V), with a 1µF capacitor connected between VDD and GND.
5	SW	passive	Switch pin of the DC-DC converter; connect a 10µH inductor between SW and VCC.
6	GND	power_in	Ground.
7	CAP	passive	Charge pump capacitor pin for the generated negative supply; connect a 220nF capacitor between CAP and SW.
8	PS	input	Power supply control pin referenced to VL that enables the integrated DC-DC converter.
9	MODE	input	Mode control pin referenced to VL that selects shutdown, receiver active, driver disabled or normal mode (Table 1), and serves as a driver enable for half-duplex use.
10	VL	power_in	Logic supply of 1.8V to 5.5V for receiver outputs, driver inputs and control inputs, bypassed to GND with 220nF if not tied to VCC.
11	TIN	input	Driver input referenced to VL.
12	ROUT	output	Receiver output referenced to VL, short-circuit protected to GND/VCC/VL and high impedance in Shutdown mode.
13	VEE	power_out	Generated negative supply for the RS-232 driver (-6.3V) on the exposed backside pad, with a 1µF capacitor between VEE and GND; must be soldered to the PCB.
